What is Roller Hearth Furnace?
A Roller Hearth Furnace transports components through a heating chamber on a series of driven rollers. The charge may rest directly on the rollers or on suitable trays and fixtures, depending on its shape and support requirements.
Roller movement and furnace temperatures are coordinated to provide the required heating and holding conditions. Loading and discharge equipment connect the furnace to the surrounding production process.
This arrangement is useful where compatible loads need to move through a repeatable treatment sequence. Component dimensions, weight distribution and stability determine whether roller transport is suitable.
Applications of Roller Hearth Furnace
PRECONS’ published roller hearth range includes stress-relieving and annealing applications for formed tubular coils and boiler pressure parts.
Stress relieving of suitable tubular assemblies
Annealing of formed tubular coils
Specified heat treatment of boiler pressure parts
Thermal processing of compatible fabricated components
Treatment of components carried on suitable fixtures
Repeat production of similar loads requiring a defined heating cycle
The material, construction and required properties determine the treatment programme. Loads must also be compatible with the roller spacing and transfer arrangement.
Roller Hearth Furnace Configurations
PRECONS develops the furnace around the charge, handling method and required output. These six design options can form part of the proposed system.
Suitable components are supported directly by the rollers. Roller spacing and load distribution are selected to maintain support throughout the transfer path.
Trays or fixtures can support components that cannot travel directly on rollers. Their dimensions, weight and thermal mass are included in the furnace design.
Working width, clearance and roller arrangement are matched to the component envelope. Load stability, transfer alignment and maintenance access are considered during engineering.
Gas-fired equipment is selected according to heating demand and available fuel. Burner positions and combustion controls are developed around the chamber and charge.
Temperature zones and roller movement are coordinated to meet the treatment requirements. Residence time is established for the specified load and production conditions.
PLC-based operation, process recording and recuperative heat recovery can be considered within the project scope. Features are selected according to the duty cycle and operating needs.
How Does a Roller Hearth Furnace Work?
The system coordinates component movement with the required thermal cycle. The exact arrangement depends on the charge and treatment specification.
Components or loaded fixtures are placed on the entry conveyor. Their position, spacing and stability are checked before transfer into the furnace.
The roller system moves the load into the working area. Transport settings are coordinated with the required heating sequence and available downstream space.
The charge passes through the specified heating conditions. Temperature settings account for the material, section thickness and fixture arrangement.
The load receives the specified time at temperature. Furnace length, operating sequence and transport rate are selected to provide the required treatment conditions.
The treated charge moves onto the discharge arrangement. Cooling and subsequent handling follow the process specification, whether provided within the line or by separate equipment.

Frequently Asked Questions
Find answers to the most common questions about Roller Hearth Furnace.
What is a Roller Hearth Furnace used for?
It moves compatible components through a controlled heating process on driven rollers. PRECONS’ published applications include annealing and stress relieving of formed tubular coils and boiler pressure parts.
How does a roller hearth furnace differ from a mesh-belt furnace?
A roller hearth supports the load on rotating rollers, either directly or through fixtures. A mesh-belt furnace carries material on a moving belt. Component geometry, weight and process requirements determine the suitable transport method.
Can components travel directly on the rollers?
Yes, if their shape and support requirements permit. Parts that could become unstable or fall between rollers may need trays or fixtures.
How is residence time controlled?
Residence time depends on the heated length and the selected transport sequence or speed. These settings must provide the required thermal exposure for the specified charge.
How is production capacity determined?
Capacity depends on load weight, spacing, treatment time and conveyor capability. Heating and downstream handling must also support the required throughput.
Can the furnace process different component sizes?
Different sizes may be processed within the agreed operating envelope. Roller support, load stability, heating requirements and settings must be checked for each component family.
Is a cooling section included?
Only where specified. The process may require an integrated cooling arrangement or separate cooling after discharge. The complete sequence is defined during engineering.
What determines the price of Roller Hearth Furnace?
Pricing depends on capacity, dimensions, operating requirements, equipment configuration, automation, accessories and project location. PRECONS prepares a quotation after reviewing the technical specifications and required supply scope.
Does PRECONS supply Roller Hearth Furnace outside India?
Yes. PRECONS welcomes international enquiries, including projects in Indonesia, the Philippines, Malaysia, Sri Lanka, Iran, Saudi Arabia, the United Arab Emirates (UAE), Qatar and Vietnam. Supply feasibility, documentation, delivery and site support are confirmed for each project.
